Some recipes go viral because they are complicated and beautiful. Egg katsu went viral for the opposite reason. It is an egg, some panko breadcrumbs and a pan of hot oil, and the result looks like a small golden cutlet that splits open to release a runny yolk.
If your feeds have been full of crunchy eggs this month, here is what egg katsu actually is, where it came from, and how to make it in your own kitchen without wrecking the yolk or filling the room with smoke.
What is egg katsu?
Egg katsu, sometimes called tamago katsu, is a raw egg wrapped in panko and deep-fried until the outside is crisp and golden. The white sets softly, a bit like a poached egg, and the yolk stays liquid or jammy depending on how long you leave it. It borrows its name from katsu, the Japanese word most people know from tonkatsu, the breaded pork cutlet. Here the egg simply takes the place of the meat.
It is worth saying what it is not. This is not a Scotch egg. The whole thing takes a few minutes, which is exactly why it caught on.
How it went viral
The version most people have seen comes from Lisa Kitahara, the Japanese Canadian recipe developer behind the cooking site Okonomi Kitchen. In a New York Times Cooking feature published on 16 October 2026, she said she expected little from it because the recipe seemed too simple. Instead, her Instagram video was nearing 10 million views, with roughly four million more on TikTok.
It is not hard to see why. The clip has everything social media rewards: eggs, deep frying, a familiar food with a twist, and a slow reveal when the knife goes in and the yolk runs out.
The idea is older than the video
Kitahara came up with her recipe independently, but breaded fried eggs have shown up before. According to the same Times report, a katsu-style egg won a 2013 recipe contest in Japan run by the Japan Poultry Association and the Japanese Egg Industry Association. The winning “Egg Fry” was a raw egg coated in panko, fried until golden and served with baby greens and a little soy sauce.
Interestingly, it is rarely found in restaurants. The dish needs a gentle hand so the yolk does not break, and that makes it awkward to cook in big batches. That is good news for home cooks, because this is one of those things that genuinely tastes best straight out of your own pan.
How to make egg katsu at home
The method below follows the approach Kitahara shares on her site and the version published by NYT Cooking. The two key ideas are simple: keep the egg supported while you coat it and lower it into the oil, and keep the oil at a steady temperature.
What you need (makes 2)
- 2 large eggs, ideally not super fresh, as slightly older eggs hold together a little better
- About 6 tablespoons panko breadcrumbs
- Neutral oil such as vegetable, canola or sunflower, enough for about 2 cm (3/4 inch) in a small saucepan
- Salt and pepper
- A large metal spoon or a square of baking parchment, plus a slotted spoon
Method
- Heat the oil in a small, deep saucepan over medium heat. You are aiming for 170 to 180C (about 340 to 350F).
- Spread about a tablespoon of panko into a rough 10 cm (4 inch) circle on a square of parchment or in the bowl of a very large spoon.
- Crack an egg on top, keeping the white from spilling over the edge. Season lightly with salt, then cover with another tablespoon or two of panko, nudging crumbs onto any bare patches without touching the yolk.
- Lower the egg into the oil, on its parchment if you used it. Spoon hot oil over the top so the coating starts to set, then peel away the paper.
- Fry for about a minute, flip gently and fry for another minute or so, until both sides are golden. A large egg usually needs around two minutes in total for a runny yolk.
- Lift it onto a wire rack, season with a pinch of salt and pepper and eat it straight away.
Before the second egg goes in, skim out any loose crumbs. Burnt bits of panko will stick to the next egg and taste bitter.
No thermometer? Use the panko test
A thermometer really does help here, because the temperature is the whole game. Too hot and the yolk cooks through before the crust colours. Too cool and the panko soaks up oil and turns greasy instead of crisp. If you do not have one, drop in a single crumb of panko. If it sinks, wait. If it fizzes and floats right away, you are ready. If it darkens almost instantly, turn the heat down and give it a minute.
What to serve with egg katsu
On its own, with a squiggle of sauce, egg katsu is a great snack. But it really earns its place when it sits on top of something else, so the yolk becomes a sauce.
The Japanese way
The classic pairing is a pile of finely shredded cabbage and plenty of tonkatsu sauce, the thick, tangy brown sauce you will find in most Asian grocery stores. If you have never had it, think of a fruity, slightly sharper barbecue sauce. A bowl of steamed rice with a drizzle of soy sauce is just as good and costs almost nothing. Kitahara also likes it on Japanese curry, and honestly that is hard to beat on a cold evening.
Western ideas that work
This is where egg katsu becomes properly useful. Use it in place of a poached egg on eggs Benedict, or put it in a soft roll with mayonnaise and shredded lettuce for a breakfast sandwich with real crunch. It is excellent on a burger. It also makes a plain bowl of noodles, ramen or garlicky spaghetti feel like a finished meal. If you like quick dinners, it is a smart topper for any of our 30-minute weeknight dinners for winter.
For sauce, tonkatsu is the obvious choice, but ketchup, sriracha, chilli crisp or a few dashes of soy all work.
Is it worth the hype?
Mostly, yes. Plenty of viral recipes look better on a phone than on a plate, but this one delivers on the promise: a crisp shell, a soft white and a yolk that runs. It is cheap, fast and fun to make. The only real catch is that you need a little hot oil and a little patience, and it does not keep. Egg katsu waits for no one, so have everything else on the table before the first egg goes in.
FAQ
Can I make egg katsu in an air fryer?
Not really. A raw egg needs to set quickly in hot oil to hold its shape and get that even crust. In an air fryer, the egg would run before the panko could crisp.
Can I use regular breadcrumbs instead of panko?
You can, but the coating will be denser and less crunchy. Panko’s large, airy flakes are what give egg katsu its light texture.
How do I keep the yolk runny?
Keep the oil at 170 to 180C and fry a large egg for about two minutes in total. Shorter gives a looser yolk, longer gives a jammy one.
Is egg katsu the same as a Scotch egg?
No. A Scotch egg is a boiled egg wrapped in sausage meat and breadcrumbs. Egg katsu is a raw egg coated only in panko and fried for a couple of minutes.
